基于红外温度传感器的温度监测系统设计摘要：开关柜在保障电力系统安全中起着关键作用。长期的运行必然会出现超负荷运转、开关老化等现象而这些现象极易导致设备局部温度升高出现安全隐患。如果没有及时排除这种隐患很可能引起设备故障甚至引发火灾损毁设备进而对工业生产、企业运作造成巨大损失。因此对开关柜内易出现高温的部分进行实时温度监测具有重要意义。针对上述问题本文设计实现了一套开关柜温度在线监测系统。系统采用红外温度传感器TS118-3进行温度信息采集传感器输出模拟信号经放大滤波处理后送入微控制器单元MSP430F247进行模数转换并完成相应的数据处理。数据处理采用多次测量取平均值的方式从而减小测量误差。最后被测目标的实时温度一方面通过液晶屏FM1602显示出来以便工作人员现场查看另一方面则通过RS232上传至计算机由上位机软件对其进行分析处理实现远程监测。本文设计的实时温度监测系统经过实验验证能实现对被测物体温度的实时监测。关键词：红外温度传感器；MSP430F247；开关柜；实时监测DesignoftemperaturemonitoringSystembasedoninfraredtemperaturesensorAbstract:Theswitchcabinetplaysanimportantroleinkeepingthesafetyoftheelectricitysystem.Inthelongtermoperationitwillappearequipmentoverloadrunningorswitchagingphenomenonandthesephenomenacaneasilyincreasethetemperatureofthedeviceandthusincurringhiddendanger.Ifthedangerisnotpromptlyeliminateditislikelytoleadtomanyproblemssuchasequipmentfailurefiredisasterwhichwilldamagetoindustrialproductionandcauseheavyloss.Thereforethereal-timemonitoringoftemperatureofswitchcabinethasagreatsignificance.Inviewoftheabovequestionsthispaperdesignsandproducesasetofon-linemonitoringsystem.ThesystemusesinfraredtemperaturesensorTS118-3tocollecttemperatureinformationandthesignalisamplifiedandfilteredprocessingthensenttoMSP430F247microcontrollerunittocompletedigitalconverterandcorrespondingdataprocessing.Dataprocessingemploysthemethodofmeasuringmanytimesandtakingaveragetoreducemeasurementerrors.ThetemperatureisdisplayedbyFM1602.ThetemperaturedatathroughRS232uploadedtothecomputerwhichisanalyzedbyPCsoftwaretorealizetheremotemonitoring.Thereal-timetemperaturemonitoringsystemthroughexperimentsverifiedthatthesystemachievereal-timemonitoringtheobject.Keywords:InfraredtemperaturesensorMSP430F247SwitchgearReal-timemonitoring目录摘要IAbstractII第1章绪论11.1选题目的及意义11.2研究技术现状21.2.1开关柜测温技术研究2
